What do EAS mods do if the car "grounds"?

[Fred Nerk]

I took the plunge this weekend and ordered the Rods from Green Oval Experience. My decision is based on
1 Cost
2 I don't go off-road as often as I want so the "inconvenience" will not be an issue.
3 I air down (and up) and may as well set the rods while I'm doing that.

My question may apply to both of the common systems electronic (Llams)or mechanical (GOE HS Rods).

What happens if the car grounds when the lift is already at +50mm?

If I'm set at off-road height and the 50mm lift is being used to raise clearance AND then the car senses a grounding; will it try to go into extended (+50mm)?

What if I then try to engage super extended mode or should this never be attempted?

Thanks from me and my CV joints ;)

With Llams, eventually (assuming the compressor is working well enough) a suspension fault will occur because the suspension ecu believes, from the current sensor signals, that the suspension should rise further but it cannot because the shocks are fully extended. The solution is to set Llams height to off or back to medium or enable the special fade-out mode, then restart the engine. The sensor signals will now match the shock position if Llams was set off or fade-out mode was enabled or not be so far from the normal values if medium was selected. Fade-out starts for a corner when the suspension is about 40mm higher than off-road height (eg off-road + Llams high) and totally faded-out when about another 40mm higher, after which actual (unmodified) sensor values are passed to the suspension ecu. Fade-out occurs on individual corners so from 1 to 4.

The vehicle would have to be really stuck if it had to be raised that high and still couldn't drive off.

With the rods, there is still enough in the system to activate an extended mode, but not enough for "super-extended". Attempting to do so will cause the system to fault, or the compressor to shut down from thermal overload. In both cases a restart should reset the system (once the compressor cools). The supplied instructions outline all this.

Thinking of ordering these like you have for the same reasons. I would interested in what you think when you get them. How easy for a novice to install and ease of setting. Much appreciated in advance.

Craig, I am not the most handy guy when it comes to mechanical things, but even for a relative schmuck like me, I found the GOE rods pretty easy to fit. Apart from a bit of hassle having to remove each wheel in turn to fit the new rods and then to put it back on, it was pretty much like the instructions said. But i am still a bit wary of the D4's air suspension system doing unexpected things, so definately use some car stands just in case .... The dry lubricant stuff also is well worth getting as I'm sure that made it easier to 'pop' the ends onto the relevant attachment points with minimal struggling in awkward positions. I have kept my original LR rods and will refit them when I sell to put the vehicle back to 'normal'. I will be trying out the rods this weekend so will then know whether the "it only takes a few seconds to change over" claim is correct for mere mortals such as yours truly (!)

Thanks for that, I look forward to your hands on review!

I didn't even remove the wheels. Just made sure I left a door open and then whipped off the old one and put the new one on. I did use a bit of vaseline :eek: to make sure they came off on went on easy. I have only used them once and it was a simple matter of switching holes whilst airing down the tyres.

Be aware that leaving a door open only inhibits height changes selected by the height switch (eg normal to access), not levelling adjustments. The system provides for downwards adjustment as load is removed even if the ignition is off and upwards adjustments if the engine is running after load is added.

Here is my experience :-)

I have fitted the GOE compressor proctection plate and the suspension rods.

The plate is a doddle to fit. Just follow the instructions.

With the rods; I started with a rear wheel which I removed. The removal of the OEM rod was fiddly. I recommend the use of lithium spray as per the instructions. I was anxious not to strain or break anything. Fitting the GOE rod is very easy. I did the other three wheels without removing them, but I did place a chassis support in place. First rod took about 15 minutes to fit. The last took seconds.

I have practised changing the rods from normal to short and back and can assure you that it is as easy as they say. Hands get dirty though so have a rag available.
